Does pericyte senescence drive BBB breakdown or result from neurodegeneration as a secondary response?¶

Research Question¶
The debate highlighted correlation between pericyte senescence and AD pathology but causality remains unestablished. Resolving this directionality is critical for determining whether pericyte-targeted senolytics could be disease-modifying versus merely symptomatic.
